\ PROCESSFOR PRODUCING PRINTED MUSIC-SHEETS.

To all whom it may concern.

Be it known that I, L'oowie Hess, a subect of the Emperor of Germany,and a resident-of the borough of Manhattan, city,

county, and State o'f'New York, have invented certain new and usefulImprovements in Processes for ProducingPrinted of which the following isa specification.

' This invention relates to certainnew and useful improvements inprocesses for producing printed music sheets.

By the use of my improved process we are not only enabledto produceprints equal in artistic efi'eet to that produced by engraving, and tosave valuable time over any method at present employed, but the negativeor reverse sketching on a tinned lead plate by a skilled workman isentirely eliminated; the designer, who by the use of my process requires"very little preliminary trainin a, being enabled to make a positiveornatural sketch with simple utensils, thus effectually reducing the costof both labor and materials. Furthermore, in case errors are made by thedesigner, they maybe readily and easily erased by means of aglasseraser, and correction may be mader without in any way affectingor'defacing the prints subsequently made in accordance with the sketch.Furthermore, the transparent sheet which, in carrying out my process,has the musicimprinted thereon may be employed over and over again, thusavoiding the necessity of storing unmelted zinc plates.

In general terms, my invention consists in first taking a sheet oftransparent paper of suitable size, producing on oneside of such sheetwith non-transparent ink the staff lines and other music symbols,placing such sheet face downwardly upon a suitably rep'ared printingsurface, subjecting saids eet and surface so produced. v

b More particularly my invention consists in taking a sheet oftransparent paper 'provided, with transparent vertical and horizontalhatching lines, printingupon one sideof such transparent sheet withnontransparent ink'the stafl line's, then lightly sketching the musicsymbols thereon, and

known manner and thenprinting jlirom I the inked wit non-transparent inkthe music symbols so sketched, placing the said transthen stamping bymeans of a metal stamp Specification of Letters Patent. Applicationfiled May 10, 1912. Serial No. 696,352.

responding parts throughout the several views, Figure 1 is a. plan" viewof a trans parent sheet provided with transparent vertical andhorizontalcross-hatching lines; Fig. 2 is a plan view of a portion ofsuch shwt after the staff lines are imprinted thereon; Fig.3 is a viewsimilar to Fig. 2 after the designer sketches the notes and othersymbols from the eomposers manuscript-thereon; Fig. 4 is a view similarto symbols in. opaque ink Fig. 5 isa section in- 'dicating a transparentsheet placed face downwardly over a suitably prepared zine plate; Fig. 6is employed in my improved process; Fig. 7 is another side elevation atright angles to Fig. 6; Fig. -8 is a top view of the stamp; and Fig. 9is a plan View of the printing surface of the stamp. y Referring nowtothe accompanying draw ings, and follow in out the preferred form of'myinvention, take a transparent sheet of paper or other suitable materialdesignated A, into which sheet is preferably imprinted transparentvertical and horizontal hatching lines representedby the light blacklines a. These-lines maybe imprinted into the paper orother mater al inany manner such as by the use. of a stencil or other suitable utensil orutensils. I

duced with non-transparent or opaque ink the music staff lines, such asI have designated b in Figs. 2 to 4.- inclusive. I then corn'poserbysketching with a pencil or other sultable utensll synibolsof music,measures and compasses as in the engraving copying maybe done by aperson having very little preliminary training, such sketched musicsymbols being represented in Fig. 3' by The pencil sketch is then inkedeither by hand or by means ,of music stamps or a music writlngmachine,.-in any event using non-transparent or opaque ink. In thepreferred form, and toproduce the best results Figs. 2 and 3 after thestamping of the music a side elevation of-a stam I proceed to print uponthe sheet thus.pro-' .proceed to copy' I om the manuscript of the sheetand plate to the action of strong light finishing the negative Intheaccompanying drawings in which similar reference characters designatecor-- using process heretofore employed except that the I the lightlines designated a.

- in the of time and labor, I use music stamps F illustrated in Figs. 6,.7 8 and 9, hereinafter described. i

The stamp F comprisesa base or stamp-i ing portion 1 of metal orothersuitable ma terial, having the note or other symbol representedthereby engraved or raised. in or on its surface, a thin flat verticalhandle 1" squared at its edges the thickness of such handle beingapproximately equal to the space between the cross-hatching lines a sothat the same may be employed as a vertical guide in stamping the symbolon the music i sheet'and a transverse guide bar f also hav- 'tancebetween the cross-hatching lines a a ing a width approximately equal tothe disand disposed at right angles to the handle By the use of thisstamp I am enabled .place the symbol; With a little practice suchsymbols maybe positioned with great accuracy.

The top of the handle preferably bears the type of. the symbolrepresented thereby so t at visible and positive representativecharacters will appear before the Stamper at all times, and if desiredthese stamps may be arranged in a type case, the outside of which showsthe corresponding symbols, and stamps of course be supplied to theoperator in various sizes conforming to all sizesof stafi' lines andspaces in use.

Having now produced a transparent'sheet with transparent vertical andhorizontal hatching lines, and with the staff lines and music symbols inopaque or non-transparent ink, I proceed to placethetransparent sheet sopreparedupon a metal plate suitably prepared with chromate of potash orother suitable chemical and subject the same tothe action of stronglight, then develop such metal plate in the usual manner so that after asuitable period of such subjectiont'o light 1,112 see 1 and subsequentdevelopment the stafi lines" and symbols .will appear upon' the metalplate in relief. These-plates may then be further finished soas toeliminate all rough surfaces, whereupon 'niusic sheets may be printedfrom the same. The .sheets thus distinct and equal in appearance tomusic sheets produced by the engraving process. 3 v 1 .Hav-ing describedmy invention, 1' claim:
